Partial dissolution of glauconitic samples; implications for the methodology of K-Ar and Rb-Sr dating

The K-Ar dating of glauconite has been used as an important stratigraphic tool for many decades. The application of this technique is limited to pure glauconites, free of detrital contamination by K-bearing phases, often not easy to detect. This study extends the application of isotope dating to the...
